Duplicator Smiles (デュプリケータースマイル, Deyupurikētāsumairu) are a type of enemy in killer7 and a type of Heaven Smile. They take the form of hive-like structures mounted on a roof or wall. Although they are immobile and can barely be considered living, Duplicators are somewhat dangerous in that they spawn other Heaven Smiles at regular intervals, although these are always of the weakest variety. They also possess a seemingly indestructible carapace and are vulnerable only in their core. Yellow cores can be destroyed easily, but red cores can only be destroyed by Dan Smith's Demon Shells.
